Inverse 0.3.0 released

Inverse 0.3.0 is out. @sweberdev/inverse and @sweberdev/inverse-react are on npm under the MIT licence, and the Pro packages are updated on GitHub Packages for licence holders. Nothing breaks: 0.2.0 code keeps working as it is.

One script tag, no React

Most shops and company sites do not run React. The new module @sweberdev/inverse/ui renders the same accessible two-step flow as the React DeclarationFlow, with labels, linked error messages, focus handling and a receipt announced to screen readers. It posts to the same handler endpoint.

On WordPress, in a Shopify theme or on a static page you only need the markup and one script:

<div data-inverse-form="withdrawal" data-endpoint="https://example.com/api/inverse"></div>
<a data-inverse-link="withdrawal" href="/widerruf"></a>

<script src="https://cdn.jsdelivr.net/npm/@sweberdev/inverse@0.3/dist/inverse.global.js" defer></script>

The script (about 9.5 kB gzipped, all languages included) mounts every marked form and fills empty footer links with the statutory label. The language follows data-locale or the page's lang. In a bundler, call it yourself:

import { mountCancellationForm } from "@sweberdev/inverse/ui"

const form = mountCancellationForm(document.querySelector("#kuendigen")!, {
  endpoint: "/api/inverse",
  locale: "de",
})

The new guide Plain HTML, WordPress and Shopify walks through it.

Dutch, Spanish and Polish

Forms, error messages, the receipt e-mail and the downloadable copy now also come in nl, es and pl, with dates in the local format. The two withdrawal button labels use the official wording of Article 11a of the directive in each language. The other texts are our translation: have a native speaker or your lawyer check them before going live. inverse check recognises the new labels.

Inverse Pro 0.3.0

• Ledger in your database. postgresStore() and sqliteStore() keep the tamper-evident ledger in PostgreSQL or SQLite through any driver (pg, Neon, PGlite, node:sqlite, better-sqlite3, Bun). The table is append-only and created on first use, two server instances cannot fork the chain, and verification, evidence sheets and retention work as before.
